I got 89/100 in C3 and I was wondering because C4 is meant to be harder would it be possible to get 91+ in C4 and get an A* I mean at the moment the past paper questions etc look relatively straight forward so would it be possible?

I did better in C2 than C1 and better in C4 than C3; just because a paper is supposed to be harder doesn't mean you'll automatically get a lower mark than you did in an 'easier' paper So yes it's possible. Just put your back into it and 91%+ is definitely achievable.

I must agree with b_white, a very good friend of mine is Chinese who finds Maths and Further Maths relatively easy, however she had to retake C4, it is super tough gaining the A* in C4, mostly because of the greater depth and synoptic nature of the unit. C3 however is not that difficult, you must also remember, the old specification P3, was always the most difficult unit, and C4 is literally the old P3 with some topics from the P2 as well.

The A* in C4, you can only lose 6 - 10 raw marks, depending on whether it is a easy or hard paper, that is difficult to achieve especially when it is so easy to make careless errors such as not calculating in Radian mode etc

Certainly you can achieve the A* if you start now, alot of people I know who are predicted A* grades in Maths, Further Maths and Chemistry only just started revising!

if you put as much effort into C4 as you did C3 then you should have no problem, the trouble a lot of people have is they don't divide the time between the two modules equally, due to C3 being the more interesting/fun. I managed to scrape an A* luckily, having scored 94 in C3 and 88 in C4.
